Calcitonin for Osteoporosis

Examples

Generic Name

Brand Name

calcitonin

Fortical,
Miacalcin

How It Works

Calcitonin is a naturally occurring hormone. It helps regulate
calcium levels in your body and is involved in the
process of bone building. When taken by shot or nasal spray, it slows the rate
of bone thinning. It also relieves pain that occurs when the bones in the spine
(vertebrae) break and collapse on top of each other (spinal compression
fracture).

Why It Is Used

Calcitonin is used in women with
osteoporosis to help reduce bone loss.

It may be prescribed for women who are more than 5 years beyond
menopause and who do not tolerate bisphosphonate medicines.

Calcitonin may be used in men with osteoporosis who have normal
levels of the male sex hormone
testosterone or whose osteoporosis does not get better
with testosterone treatment.

Calcitonin may relieve pain caused by spinal compression
fractures.

How Well It Works

Calcitonin slows thinning of bone, and may help relieve pain from broken bones
caused by osteoporosis.1 It may also decrease the risk of fractures in the spine.2

Side Effects

All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

Here are some important things to think about:

Usually the benefits of the medicine are more important than any minor side effects.

Side effects may go away after you take the medicine for a while.

If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.

Call 911 or other emergency services right away if you have:

Trouble breathing.

Swelling of your face, lips, tongue, or throat.

Call your doctor if you have:

Hives.

What To Think About

It may take up to 2 weeks before pain relief is noticed. Not all
people who take calcitonin get relief from their pain.

Taking medicine

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.

There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.

Checkups

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
